Green TeaGreen tea is an essential part of people’s everyday life around the world; it is tasty and healthy but is that all there is to it? Most people in Europe and Asia prefer green tea over other beverages as it is light and energizing. China, where tea came from, is the center of green culture; Chinese people have much higher life expectancy due to living healthy and drinking green tea.

As many people know “the history of green tea began in China” (Learn all about the History of Green Tea). Some sources claim that there are references to green tea as far as 5000 year ago. It can be true because many ancient Chinese artists portrayed wealthy people drinking tea (Painting). Also tea in ancient China was a treat for the wealthy so it could’ve taken some time to develop. There are two legends about where tea came from circulating the world. First one says “an old man accidently stepped on a fallen tea leaf and tasted its juices, he thought it tasted great and had some special properties” (Learn all about the History of Green Tea). Second one tells that an “Emperor Shen Nung discovered tea when a blossom fell in his cup” (Learn all about the History of Green Tea).With time tea became more than just a drink but a part of the Chinese culture. Drinking tea wasn’t just about the tea, a whole new “tea art” was developed. “Tea and tea wares should match surrounding elements such as breeze, pines, bamboo, plums and snow. All there show harmony of human and nature” (Tea Culture). It is easy to understand why tea is so important once you come across a tea ceremony or read one if the many books about it. In the painting you can see that wealthy people were drinking tea and the peasants were making it. The reason why only people of high class could afford tea is because the ceremony was a very complex practice which required pricy equipment and skilled laborers. A proper tea ceremony requires extensive...

The American Cancer Society explains:
“Greentea contains chemicals known as polyphenols, which have antioxidant properties. The major group of polyphenols in greentea are called catechins, and the most important catechin seems to be epigallocatechin gallate (sometimes calledepigallocatechin-3-gallate or EGCG). EGCG may help cause certain types of cancer cells to die in much the same way that normal cells do. This effect is important because cancer cells are different from normal cells in that they do not die when they should—they continue to grow and spread.”

...for the purification of the targeted compound. Based from the data collected, 5.758g of tea leaves contains 3.96% caffeine. After the purification process, 0.2279g of caffeine was obtained from 0.4948g crude extract with 46.06% yield. Melting point determination was used to characterize the caffeine yielded. However, the melting point range of the caffeine collected (190°C -215 °C) was lower than the melting point of the accepted value (238 °C) which may be due to experimental errors committed in the extraction and washing process.
Introduction
Tea has been consumed as a beverage for almost 2,000 years starting in China. It is the most widely consumed beverage after water [1].Their active participation in trade resulted in its introduction to Europe. The active component in tea is caffeine (C8H10N4O2). Caffeine belongs to an extensive class of compounds known as the alkaloids. Alkaloids are a diverse group of compounds that are found primarily in plants and contain basic nitrogen atom(s). The basic nature of these compounds makes them exists mostly as salts.

Abstract
Tea leaves are natural products that are harvested from agriculture. Caffeine, on the other hand, is a stimulant that has been shown to speed up the time of reaction, increase alertness, and improve one’s concentration. What we did in this experiment was to extract the alkaloid caffeine content from the tealeaves. We had isolate and purify the leaves in the teabag so that we could acquire what is called a “pure caffeine.”
Introduction
Beverages such as tea and coffee consist of high amounts of caffeine. Caffeine is a stimulant that enhances one’s concentration and alert level. Caffeine is classified as an alkaloid, which is used for substances produced as end products of nitrogen metabolism in some plants. It is also among a large group of nitrogenous substances found in natural plants. Although the plant may be poisonous and may be bitter-tasting, many of its extracts are pharmacologically active and may cause a person to have changes in his psychology. Some examples of alkaloid are atropine, coniine, morphine, nicotine, quinine, and strychnine.
In the experiment, we had to isolate, which is to separate a substance in pure form from a mixture; purify, which is to rid the tealeaves of impurities; and characterize, which...
